IMPROVEMENT IN ANIMAL-POWERS.

Specication forming part of Letters Patent No. 131,495, dated September24, 1872.

This invention relates to the construction of a power to be propelled bya dog or other similar-sized animal to be, employed for churning butter,pumping water, and other suitable purposes, and is described as follows:

Referring to the drawing, Figure 1 is a top or plan view. Fig.2 is aside elevation,vand Fig. 3 is an end elevation, of my above-mentionedinvention.

A is a base-board on which stands the superstructure, across which andnear the end are fastened cross-pieces B B. Secured to the cross-piecesB B are upright supports O O, providedV at the upper end with an archedratchet-bar, D the purpose of which will be hereinafter shown. E is aframe, which stands .between the uprights O O, and which has itsbearings at the lower corners in the central part of the cross-pieces BB. In this frame E is arranged the running parts of the niachine. In themiddle of said frame is an upright shaft, F, having a stop in the lowerrail of the frame E and its upper bearing in the upper `rail. Secured tothe shaft E is a treadwheel, G, upon the broad rim of which a dog is totravel. The tread-wheel is steadied by brace-rods H H, reaching from theinner circle of the rim to a collar, I, on the shaft. On the undersideof the wheel and forming a part of the hub thereof is a cog-wheel, J,which gears with a pinion, K, on a horizontal shaft, L, said shafthaving one bearing in a short post, M, in the frame E, and the other inthe end post of the said frame, the end-of the shaft carrying a driving-pulley, N, from which power may be transmittedfor useful purposes. Onthe top of the shaft F is attached a segmental rack, O, in which areplaced two arms,

P P, on which are balls Q Q, said balls being adjustable on the arms bymeans of pins. The arms are also adjustable in the rack O, by which theymay be placed at different angles of elevation. Along the side of thetop rail of the frame E is a shaft, R, having its bearings in pla-tes SS at the ends of said top rail. Ou said shaft R are two small pinions, TT, which gear with and play in the curved rack D, the end of said shaftR having a crank, U, for turning the same, and which may be secured indifferent positions by a pin passed through the crank and the plate S.The object of this arrangement is to' tilt the fra-me E and give thetread-wheel a slant which greatly facilitates the movement ofthe dog.The object of the arms P P and balls Q Q is to give momentum to themotion of the treadwheel, and also to aid the dog, they acting' as abalance-wheel. creased more or less bychanging the distance of the ballsfrom the center of motion. Guideframes V V are attached to the frame Efor keeping the dog in proper place and direction on the tread-wheel. Asecond post, M2, is placed in the frame E, so that another shaft likethat of L may be put in the frame, if desired, for doubling the capacityof the machine.

I claim- 'Ihe tread-wheel' G, upright shaft F, gear J, pinion K, shaftL,pulley N ,rack O, arms P P, balls 'Q Q, and the frame E, shaft R,pinions T T, crank U, curved rack D, supports O O, cross-pieces B B,guide-frames V V, all constructed, combined, and arranged to operatesubstantially as and for the purpose set forth.
